transform.position not executed with OnTrigger2D
Hello everyone. I'm trying to script enemies AI, by using triggers. My goal is to use a transform.position when player enters inside enemy trigger.
Here is my code (my game is 2D with top-down movement just like beat'em up games) :
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class EnemyAI : MonoBehaviour
{
public float speed;
public Transform target;
bool triggered = false;
void Start()
{
target = GameObject.FindGameObjectWithTag("Player").GetComponent<Transform>();
}
void Update()
{
if (triggered == true)
{
transform.position = Vector3.MoveTowards(transform.position, target.position, speed * Time.deltaTime);
Debug.Log(triggered); //I used this debug.log to see if function changes to true
}
}
void OnTriggerEnter2D(Collider2D other)
{
if (other.gameObject.tag == "Player")
{
// Debug.Log("Hello");
}
}
void OnTriggerStay2D(Collider2D other)
{
if (other.gameObject.tag == "Player")
{
Debug.Log("Going to hit you");
triggered = true;
}
}
void OnTriggerExit2D(Collider2D other)
{
if (other.gameObject.tag == "Player")
{
Debug.Log("bye");
triggered = false;
}
}
}
With debug.log messages I managed to test my boolean triggered, it triggers with messages displayed inside console, but my enemy does not want to move.
I also tried to put the transform.position directly inside void update, once I hit play enemy begins to move towards me.
Where is the problem ?
Many thanks to anyone who can find out.
Is it a 2D game or a 3D game? I just ask because you have 2D trigger colliders, but it appears your movement is in 3D with Vector3.$$anonymous$$oveTowards
It's a 2D game, but the movement works when looped inside void update() without any boolean. I do not think it's a part of issue.
Ok, but you can change Vector3.$$anonymous$$oveTowards to Vector2.$$anonymous$$oveTowards. I can't see anything else wrong with your code. I'll take a look at your project if you want to send a zip folder
Find a solution ! Attached a Rigibody to both Player and Enemy, with Kinematic as Body Type and "Never Sleep" as Sleeping mode. Then I changed OnTriggerEnter2D to OnTriggerStay2D and it's working !
